. F.A HENRARD MIXER .Filed oct. 4L 1929 Sulk , /M/f/y To@ Patented May 26., 1931 i UNITED STATES PATENT AOFFICE FERNAND HENRARD, or BRUSSELS, BELGIUM MIXER Application filed October 4,' 1929. Serial No. 397,281.

Under agricultural conditions at present in existence the whey, after separating the milk therefrom, generally serves as food for animals. The nutritive value of this-whey 5 is, however, very low as it only contains af rator on which are disposed accessory mem-` bers to adapt the same for use as a mixer.

According to the invention thel mixer l5 serves as means for effecting the mixing o f a fatty body and the whey while they are being subjected to a rotary movement. The invention also provides that the mixture of the whey and the fatty body maybe 20 obtained by spreading or dispersing the fluid, containing the fatty body and the whey, in the form of a stream in a sleeve.

For the purpose of effecting the said dispersion of the fluid, the sleeve may be pro- 25 vided interiorly at the upper portion thereof with blades disposed in the form ofV a helix; and itl may also be provided in its interior with axial ribs in order to obtain a more eficientmovement of the mixture.

Finally a more eflicient balancing of the said sleeve may be obtained by employingV a disc arranged at right angles to the axis of the sleeve.

The accompanying drawings illustrate by 1 way of example and in a non-limiting manner, two forms of construction in accordance with the invention. The invention includes various features which will appear from the following description.

ln the accompanying drawings Figure l is a perspective view, partly broken away, of the improved device for mixing the whey with a fatty body.

Figure 2 is a part-sectional perspective view of the mixing sleeve.

Figure Sais a perspective view of a mixer for mixing the whey and the fatty body having a device for determining the content of fat in the milk.

The mixer shown in Figure 1 is provided '2g leading into the upper portion of the casmixer.

yportion of the said sleeve.

with a milk tank 2a, a driving mechanism 2b, a protecting casing 2d and a support 2f serving to carry, a tank 3 adapted to contain a fatty body, and a device 4 enabling the fatty body'to be mixed with the whey by imparting a rotary movement to the two substances. The whey content in the tank 2a and the fatty body content in the tank 3 are passed into a distributor 270 provided with a spout ing 2d. 0 For the purpose of driving the mixing device 4, the latter, which is formed by a sleeve la (Figure 2), is connected inechanically to the driving mechanism 2?) of the For the purpose of obtaininginti-V mate mixing of the fatty body and the whey, these substances are conducted by the spout 2g into the truncated open upper end llt' ofA the sleeve la where they are divided into a stream by reason of the vertical blades im arranged in the form of a helix in the upper' These blades arranged at 120 apart, are connected together at their lower portion 471, where they are pro- L videdvwith a central orilice not shown in the drawings.

In order to obtain a more efficient movement of the mixed fluid, whichV is'projecte'd against the inner wall of the sleeve 4a, the sa latter is provided integrally with axial ribs. i 4g; and to balance the sleeve 4a a disc 4d, cast integral with the sleeve, is arranged at right angles to the axis of the sleeve.

The connection of the sleeve 4a to the shaft 2m of the driving mechanism 2b ofthe mixer is effected by meansV of a truncated rod 4k, which is provided at its upper end with-an' eye 4f adapted to `be engaged by a hook on theV shaft 2m. The'lower reduced and screw threaded end 4p of this rod passes through i the central orifice provided in the lower portion ln of the blades lm and is secured there-4 to by a nut 41'.

The. invention also includes the feature of I According to the invention the testing device 5 (Figure 3) is disposed above a gear train of the driving mechanism 2b and is connected to the mechanism of the mixer.

The testing device 5 is provided with two cylindrical bodies such as 5a, mounted substantially horizontally in a circular dished plate 52),se'cu`red by a screw, not shown in the drawings, to the frame work of the mechanism 2b.

The two bodies 5a, of substantially the same diameter and secured to a hollow shaftj 5g, enclose between them graduated tubes 5b which dip into Jthe milk contanedfinfthe said bodies 5a and of which it is desired to determine'the content of fat.

In order toavoid any accident during the rotation of the cylindrical bodies 5a, the hollow' shaft 5g ismounted withslight friction on the shafttso as to slide on the shaft 21: when the bodiesar meet with a certain resistance during tneir' movement. This shaft 2t is the driving shaft of the mechanism QU of thefmiXe/r and isdriven by meansk of a beltby an electric motor 2s.

For the purpose of protecting the bodies a'against externaliniiuences a cover 5a is placed onthe plate' 5p:

Accordinfr `to the invention; the-mixer as` illustrated in Figure Bserves both as a'support foil the tank 3 and the testing device 5.
